Pipeline type filter material collection device

Abstract

The invention relates to the field of water supply and drainage, in particular to a pipeline type filter material collection device. The pipeline type filter material collection device comprises an outer sleeve and a plurality of filter plates. Each filter plate is provided with a plurality of filter holes, the filter plates are coaxially arranged in the outer sleeve in a stacked mode, and a gap is formed between every two adjacent filter plates. A water outlet is formed in the upper end of the outer sleeve, a filter material collection opening is formed in the lower end of the outer sleeve, a water inlet is formed in the side wall of the outer sleeve, and the filter plates are arranged between the water inlet and the water outlet. The pipeline type filter material collection device guarantees smooth sewage discharge and reduces or even avoids the situation that a filter material is washed away, so that a better backwashing effect is achieved for a filter pool or a filter tank, filter material consumption is reduced, the operation cost is lowered, and long-term stable operation of filter equipment is facilitated.

Description

technical field [0001] The invention relates to the field of water supply and drainage, in particular to a pipe-type filter material collection device. Background technique [0002] Unshaped filter materials include quartz sand, manganese sand, activated carbon, ceramsite, multimedia, microporous particles or other granular materials. [0003] Traditional filter tanks or filter tanks made of unshaped filter materials tend to cause filter materials to flow out with backwash sewage or gas during backwashing, resulting in waste of filter materials. [0004] In order to avoid the waste of filter material, metal mesh is mostly used in the prior art to block, but such effect is very poor. Although the mesh aperture of the metal mesh is too small, it can temporarily block the filter material, but it also affects the smooth discharge of backwash sewage, often causing blockage. The larger the mesh aperture, although it can reduce the discharge resistance of backwash sewage, but the...

[0003] Traditional filter tanks or filter tanks made of unshaped filter materials tend to cause the filter materials to flow out with the backwash sewage or gas during backwashing, resulting in waste of filter materials

[0004] In order to avoid the waste of filter material, the existing technology mostly uses metal mesh for blocking, but the effect is very poor

Although the mesh aperture of the metal mesh is too small, although it can temporarily block the filter material, it also affects the smooth discharge of backwash sewage, often causing blockage

The larger the mesh aperture, although it can reduce the discharge resistance of backwash sewage, but the loss of filter material will also increase.

It is difficult to find a balance between the two in actual work, so an equipment structure is needed that can not only discharge sewage smoothly but also prevent the loss of filter material
